Several soon-to-be free agents are on the cusp of being some of the biggest bargains on the market.

Philadelphia 76'ers center Andrew Bynum did not play last season due to knee injuries. According to Sporting News, Bynum underwent bilateral arthroscopic surgery in mid-March.

Dr. David Altchek of the Hospital for Special Surgery in New York, Bynum's longtime orthopedist, performed the surgeries, according to the team. The primary focus: Cleaning out loose debris from within the joints in an effort to relieve chronic pain and swelling.

The center earned $16.1 million last season in the final year of a four-year contract worth more than $57 million, according to Spotrac.

Due to the concerns about Bynum's health and passion for basketball after he didn't play last season, there could be limited interest in the center in the offseason. If a team signs Bynum for less money than his previous contract but gets production similar to the 18.7 points and 11.8 rebounds per game that he averaged in 2011-12 for the Lakers, Bynum has the talent to be a steal if given a smaller contract.

Chris "Birdman" Andersen signed two 10-day contracts with the Miami Heat before signing for the remainder of the season for $540,000. In the playoffs, he is averaging 6.9 points and 3.8 rebounds per game to go along with his 81.8 shooting percentage. Andersen is limited offensively and he will struggle to continue shooting as well as he has in the postseason but his production with Miami should garner some attention in the open market.

Kenyon Martin

According to Spotrac, Kenyon Martin started his season with the Knicks in mid-February when he signed the first of two 10-day contracts. New York eventually him for the remainder of the season for $270,000.

Andray Blatche

After being amnestied by the Washington Wizards last summer, Andray Blatche signed a one-year contract with the Brooklyn Nets worth $1.1 million.

Blatche played an average of only 19 minutes per game last season as the backup center but averaged 10.3 points and 5.1 rebounds per game.

He was the 80th highest paid center last season but had the 29th best PER among centers.

While Blatche made more than $23 million, which he was scheduled to earn over a three-year span, after being amnestied by the Wizards, the free agent market said that he was worth barely more than one million dollars last season.

That figure could increase in the offseason for the eight-year veteran but if Blatche can repeat his production next season, he would be worth the cost.

He has started at least 81 regular season games in three of his five seasons, proving his ability to be a durable starter. Mayo increased his average assists per game by 1.8 from the 2011-12 season to last season, showing his ability to get his teammates involved.

Depending on how much he signs for in the offseason, Mayo's track record as a young shooting guard shows that he can become even better and have tremendous upside in the future.

Darren Collison

Despite having his yearly statistics plateau through his first four seasons, Darren Collison is a talented young point guard.

Collison averaged 12 points and 5.1 assists per game in the final option year from his rookie contract. He was the 36th most efficient guard in the NBA last season in a year in which he earned $2.3 million, which made him the 51st highest paid point guard in the league.
